The 3 D reconstruction of inner ear done with post-processing by maximum intensity projection(MIP) and multi-planar reconstruction(MPR) where as thin axial sections combined with 3 D reconstruction of inner ear by using 3D-FIESTA sequence precisely show IAC with 7th 8th CN Complex, Trigeminal CNs and Inner ear as well as the relationship between lesions and structures in and around IAC.
A case of left facial hemi spasm, MRI Brain axial sections of FIESTA shows tortuous left vertebral causing left side 7th - 8th CN complex compression.
A case of right side trigeminal neuralgia shows tortuous basilar very close to cisternal portion of right side trigeminal nerve causing mild displacement of nerve.
